Abstract
Many techniques on holographic mass storage systems have been developed, which scalar and vector optical data are stored in holographic materials. To realize high data transfer rate, binary SLM such as a ferroelectric liquid crystal SLM and a digital micro-mirror device (DMD). Therefore, methods to increase the recording density using binary data pages are proposed. The principles of the method are verified by numerical analysis and experimentsTwo shot recording for 4-level phase multiplexing is performed by a high-speed binary intensity SLM using a ferroelectric liquid crystal (FLC). Experimental results are presented in terms of recording capacity.
